California's winter tule fog—hated by drivers, but needed by fruit and nut trees—has declined dramatically over the past three decades, raising a red flag for the state's multibillion dollar agricultural industry, according ...

Southern Oscillation is known to influence global surface temperatures, with El Niño conditions leading to warmer temperatures and La Niña conditions leading to colder temperatures. However, a new study in Geophysical Research ...

Wildfires across the western United States have been getting bigger and more frequent over the last 30 years – a trend that could continue as climate change causes temperatures to rise and drought to become more severe ...

The headwaters for Puget Sound's famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest's inland ...

New radar measurements of an enormous sea on Titan offer insights into the weather patterns and landscape composition of the Saturnian moon. The measurements, made in 2013 by NASA's Cassini spacecraft, reveal that the surface ...

Geophysical Research Letters

Geophysical Research Letters is a publication of the American Geophysical Union. GRL is the organization's only letters journal. Since its introduction in 1974, GRL has published only short research letters, typically 3-5 pages long, which focus on a specific discipline or apply broadly to the geophysical science community. The shortness of its papers expedites peer review and the publication process, which allows for rapid dissemination of new scientific results.

The Editorial Board of GRL evaluates manuscripts according to the following criteria:

The AGU provides subscribers access to electronic versions of nearly all papers published in Geophysical Research Letters from 1994 to the present. In addition, since 1994, the AGU has provided online e-supplements to GRL articles, allowing data sets to be disseminated and archived along with electronic versions of the published articles.
